CTR formulas
CTR stands for click-through rate. It measures the percentage of impressions that generate a click.
Worked CTR examples
2,500 clicks from 100,000 impressions equals a 2.50% CTR.
100,000 impressions at a 2.50% CTR would generate about 2,500 clicks.
To generate 2,500 clicks at a 2.50% CTR, you would need about 100,000 impressions.
If your current CTR is 2.50% and your target is 3.00%, the campaign is below the target CTR.
What CTR tells you
CTR helps show how often people click after seeing an ad, email, search result, or other clickable message.
Changes in headline, creative, audience, placement, and offer can influence CTR, making it useful for testing campaign variations.
Expected CTR can be combined with impression forecasts to estimate the number of clicks a campaign may generate.
CTR vs. CPM and ROAS
CTR measures how often impressions turn into clicks. CPM measures the cost of buying 1,000 impressions. ROAS measures advertising revenue compared with advertising spend. A high CTR can be encouraging, but it does not automatically mean a campaign is profitable.
Frequently asked questions
What does a 2.5% CTR mean?
It means about 2.5 out of every 100 impressions resulted in a click, or about 25 clicks per 1,000 impressions.
Is a higher CTR always better?
Not necessarily. A higher CTR means more clicks per impression, but the quality and profitability of those clicks still matter. Conversion rate, cost, revenue, and ROAS should also be considered.
How do I calculate clicks from CTR?
Multiply impressions by CTR and divide by 100. For example, 100,000 impressions at a 2.5% CTR equals about 2,500 clicks.
How do I calculate required impressions?
Divide the desired clicks by CTR, then multiply by 100. For example, 2,500 clicks at a 2.5% CTR requires about 100,000 impressions.
What is a good CTR?
There is no universal good CTR. Benchmarks vary by channel, placement, industry, audience, creative, device, and campaign objective. Compare your result with relevant benchmarks and your own historical performance.
Why can a high CTR still produce poor results?
Clicks may be low quality or fail to convert. A campaign can attract attention while still producing weak conversion rates, revenue, or ROAS.
